EPIC has
filed a complaint
with the FTC asking the Commission to investigate Google's tracking of in-store
purchases.
According to EPIC, Google collects
billions of credit and debit card transactions and then links that
personal data to the activities of Internet users.

Google claims that it
protects online privacy but refuses to reveal details of the
algorithm that "deidentifies" consumers while tracking their
purchases. EPIC's complaint asks the FTC to stop Google's tracking
of in-store purchases and determine whether Google adequately
protects consumer privacy.
